Learning Objectives
- Describe the location, function, production, circulation, and drainage of CSF
- Describe how the blood-brain barrier protects the central nervous system
- Demonstrate the origin, course, and major branches of the common, internal and external carotid arteries and locate the carotid pulse
- Describe the arrangement of the pia, arachnoid, and dura mater within the cranial cavity and in relation to the brain Describe the reflections of the dura mater and the formation of the venous sinuses
- Describe the anatomy of the dural venous sinuses. Explain the entrance of the cerebral veins into the superior sagittal sinus in relation to subdural haemorrhage. Explain how connections between sinuses and extracranial veins may permit intracranial infection.
Ventricular System

- what structure did the 4th ventricle develop from?
- what structure is the 4th ventricle continuous with?
CSF Circulation & Blood-Brain Barrier
- what is the function of the ventricular system?
- what are the structural components of the choroid plexus?
- where does CSF flow? how does it enter subarachnoid space?
- how and where does CSF drain?
